I answer myself, in reality I am also getting errors in some values ​​that the Mib presents to me as integers

When the expressions are integers it receives perfectly but when they are octet strings I get an error because the types do not match. I have tried everything possible, including indefinite, but there is no way that it works.

Best regards
